1. Is it true to say that, current decreases when passing through a resistor and then increases again upon exiting?

2. Is it true or wrong to say that, Magnetic fields exert a force on all moving electrically charged particles?

The air is less dense at higher elevations, so skydivers reach a high terminal speed. The highest recorded speed for a skydiver was achieved in a jump from a height of 39,000 m. At this elevation, the density of the air is only 4.

A dense mix of dry, hot rock fragments and hot gas erupting from volcanic vents at high speed is

Where did the asteroids in the asteroid belt come from?

When 450-nm light is incident normally on a certain double-slit system the number of interference maxima within the central diffraction maximum is 5. When 900-nm light is incident on the same slit system the number is: a. 9b. 2c. 3d. 10e. 5
